According to flag etiquette we are not to draw on or change the flag's appearance. That said, what you are going to do is to enhance the flag and that certainly doesn't show disrespect. I regularly repair the two flags we fly each day, just resewing the seams that come apart from the wind whipping it around. I would liken what you are doing to adding a picture of the Tower of London to the Union Jack, it certainly isn't a sign of disrespect. Anyway that is probably way more than you ever wanted to know when you asked a very simple question.
